Overhead Electromagnet
Overhead Electromagnets are suspended over conveyor belts and vibratory feeders. They are designed to magnetically lift ferrous metals out of bulk material which ensures product purity and protects processing equipment. Any ferrous metal that is attracted to the magnet face is either automatically and continuously removed with our self-cleaning models or held in place on stationary models until the magnet is turned off. Our Overhead Electromagnets remove damaging ferrous tramp metal, which can cause costly repairs and downtime.
20-Year Warranty on Coil Burnout for Overhead Electromagnets
THE BEST WARRANTY IN THE INDUSTRY!
Our electromagnet coils are wound with an anodized aluminum strap; an exclusive design that generates more magnetism than any other electromagnet on the market and exceeds Class “H” insulation rating! This design outlasts and outperforms “conventional” round wire coils that can lead to coil burnouts.
Dings Electromagnetic Coils
Dings electromagnetic coils are wound with an anodized aluminum strap; an exclusive design that generates more magnetism than any other electromagnet on the market and exceeds Class “H” insulation rating! This design outlasts and out-performs copper wire with polymer insulation or bare aluminum with Nomex® insulation.
Dings electromagnetic coils stay cooler – operating at a much lower temperature. Since electromagnets perform best at lower operating temperatures, this design ensures Dings electromagnets are stronger and more efficient. With “conventional” round wire coils, inside turns are not cooled evenly and product hot spots that damage coils. Each turn of the Dings electromagnetic coil is exposed to oil-cooling and is in constant contact with oil, therefore, eliminating the need for an oil expansion tank. Oil is free to flow around and in between each coil to maximize cooling effect.
- 20-Year Warranty on coil burnout
- No insulation needed – eliminating the major cause of coil failure (insulation breakdown)
- More magnetism and separating power – generated by extra turns
- Each turn is exposed to oil-cooling (assuring a stronger, more efficient magnet)
- Eliminates the need for external oil expansion (less pipes or tanks that can easily be damaged)
Self-Cleaning Magnetic Separators
Self-Cleaning Magnetic Separator Models have a belt that continuously travels across the face of the magnet body to automatically discharge attracted ferrous metal away from the magnetic zone. These powerful models come equipped with a heavy-duty rubber belt to remove ferrous metal from the material stream. Other cleat styles and sizes are available for use in different ferrous recovery applications. To drive the magnetic belt, a direct gear motor is used and also available in special voltages.

Turnbuckles
Facilitates the final adjustment of the magnet’s suspension height.
Zero Speed Switch
This motion control safety sensor signals when the magnetic separator belt has stopped moving.
Belt Alignment Switches
This motion control safety sensor is used to monitor belts for misalignment. If the belt has tracked too far to one side of the magnet, the misalignment switch will shut the belt down preventing costly repairs and downtime.

Dings Armor-Clad
Dura-belt
A metal clad belt developed by Dings Co. Magnetic Group as a long-life magnet cleaning belt for installations where many sharp-edged iron objects are encountered—especially useful when recycling concrete with rebar. Continuous impacts from sharp steel can cause rapid wear on standard cleaning belts. The entire impact area on a ‘Durabelt’ is protected with an armored barrier of thick stainless-steel pads. The self-cleaning belt travels continuously around the magnetic separator, automatically discharging the attracted ferrous. Individual plates can be easily replaced in the field, saving costs on belt replacement and reducing downtime.
3-Inch Rubber Cleats
Vulcanized cleats typically used in recycling applications where large ferrous metal is better carried away by 3-inch high cleats versus our standard 1-inch high cleats.
High Temperature Belt
These belts are designed to withstand temperatures of up to 200ºF and are certified to meet CSA (Canadian Standards Association) standards for use in Canada.
Special Motor Voltages
Special motor voltages are available to meet any specific application requirements.

Stationary MAGNETIC SEPARATORS
Stationary Magnetic Separator models are maintenance-free (other than maintaining oil in the electro) with no moving parts (no lubrication, no tightening or replacing of hardware needed). Ferrous metal is pulled out of the material stream to the face of the magnet and held in place until the magnet is turned off. Designed for easy installation; this model comes with a 3-point suspension system that includes two cables and one turnbuckle connected to a common bull ring. Adjustment of the magnet suspension angle is easy and only involves adjustment of the turnbuckle. There is no measuring, shortening, lengthening or cutting of cable required. These magnets are constructed with a stainless-steel bottom wear plate over the impact area.

Inline vs. Crossbelt Mounting Positions
Dings overhead electromagnets are suspended over conveyor belts or vibrator feeders in two configurations: Inline and Crossbelt.
Inline Mounting Position
Inline orientation sometimes used in conjunction with a splitter is ideal because the material is fully airborne and the tramp metal is liberated making it easier to separate. This orientation permits the use of a smaller magnet compared to cross-belt over the conveyor orientation because the suspension height is reduced and tramp metal is magnetically separated while airborne instead of being pulled thru the material burden as it’s being conveyed.
Crossbelt Over Conveyor
In a cross-belt over the conveyor belt mounting position the electromagnet is installed at a right angle to the travel direction of the material on the belt. Tramp metal is collected by the magnet and discharged by the magnet’s self-cleaning belt into a collection bin along side the conveyor. This orientation is commonly used when the magnet is being installed in an easily accessible area on an existing conveyor.
Crossbelt Over Pulley
The cross-belt over the pulley orientation results in a more efficient use of the electromagnet since the conveyor belt flattens as it reaches the pulley allowing for a reduced suspension height. The material is also becoming airborne liberating the tramp metal and making it easier to separate. This orientation may permit the use of a smaller magnet and tramp metal can be collected in a bin alongside the conveyor.
